简单的游戏清单

Question

所以我再次尝试以正确的方式发布此内容，但我正在努力将项目添加到一个非常简单的基于文本的类项目的游戏的库存中。输出应如下所示：

You are in (room)
Inventory: []
You see a (item)
What do you wish to do?

在我的游戏中，玩家将输入类似get Sword 的命令来拾取物品。如果该项目不在他们所在的房间中，则应输出You cant get that item here。一旦玩家在房间里拿到了物品，它应该被添加到物品栏中并从房间中移除，这样输入就会显示：

You are in (room)
Inventory: [Sword]
You dont see anything useful
What do you wish to do?

我无法更新库存，然后该物品不再在房间里。当我在房间里时，我试图拿到该物品，即使物品在房间里，它也会显示You cant get that item here。 以下是我的代码的简化版本，非常感谢任何帮助。

# A dictionary for the simplified text game that links a room to other rooms.
rooms = {
        'Entrance Hall': {'North': 'Great Hall', 'East': 'Gallery', 'West': 'Library', 'item': 'None'},
        'Library': {'East': 'Entrance Hall', 'item': 'Book'},
        'Gallery': {'West': 'Entrance Hall', 'item': 'Sword'}
    }

instructions = 'To move type: go North, go East, go West, go South' \
               'to get items type get Item, ex: get Sword\n '

directions = ['go North', 'go South', 'go East', 'go West']
pick_up_items = ['get Ale', 'get Book', 'get Armor', 'get Sword', 'Necromancer', 'get Knife', 'get Candle']

print(instructions)
current_room = 'Entrance Hall'
item_in_room = 'None'
inventory = []

while True:
    print('You are in the {}.'.format(current_room))
    print('Inventory:', inventory)
    if item_in_room == 'None':
        print("You don't see anything useful")
    else:
        print('You see a', item_in_room)

    # gets the users input
    command = input('\nWhat do you wish to do? ')  # this controls the movement
    if command in directions:
        command = command.split()[1]
        if command in rooms[current_room].keys():
            current_room = rooms[current_room][command]
            item_in_room = rooms[current_room]['item']
        else:
            # if the player inputs a bad movement
            print('You cant go that way!')
    # Checks to see if the player types a 'get' command and adds the item in the room to the players inventory.
    if command in pick_up_items:
        command = command.split()[1]
        if command in rooms[current_room].keys():
            inventory.append(current_room['item'])
        else:
            # if the player inputs a item not in the room
            print('You cant get that item here!')

Answer 1

据我所知，您的物品检查有误。 您的商品在rooms[current_room]['item'] 而非rooms[current_room].keys() 中

if command == rooms[current_room]['item']:
    inventory.append(rooms[current_room]['item']) #another error i found out
    rooms[current_room]['item'] = 'None' #make sure that you check that command isn't None or it will be added as an Item
# other stuff

如果您打算在一个房间中放置多个项目，我建议您将所有字典中的item 键转换为列表，以便于检查。此外，go item 也会通过您的方向检查并引发错误。
